Seachem Flourish Phosphorus
Seachem Flourish Phosphorus is a nitrate-free phosphorus supplement for planted aquariums, designed for aquarists who need to adjust phosphate levels according to the needs of their aquatic plants. It provides phosphorus as a 4,500 mg/L phosphate solution of potassium phosphate and is safe for invertebrates such as shrimp.
Key Benefits
- Supplies phosphorus, one of the three essential plant macronutrients in the NPK group: nitrogen, phosphorus and potassium.
- Provides a nitrate-free way to dose phosphate without adding nitrate at a fixed ratio.
- Helps address phosphorus as a potential limiting factor in a flourishing planted aquarium.
- Allows more precise phosphate dosing for planted tank fertiliser routines.
- When used as directed, supports aquatic plant growth without enhancing algae growth.
How to Use
Add directly to the aquarium water as part of your planted aquarium fertiliser programme. For maximum benefit, use with Seachem Flourish Nitrogen and Seachem Flourish Potassium. Monitor phosphate levels with Seachem MultiTest: Phosphate when targeting a specific level.
Dosage
- Beginner: Use 2.5 mL (half a cap) for each 80 L (20 US gallons) once or twice a week, or as needed in response to signs of phosphorus deficiency such as stunted growth or dark green plants.
- This dose raises phosphorus by 0.05 mg/L (0.15 mg/L phosphate).
- Phosphate levels generally range from 0.15–1.0 mg/L, although the ideal level varies between aquariums.
- Targeted dosing: Use 0.8vp=m, where v = aquarium volume in gallons, p = desired phosphate increase, and m = volume of product to use in mL.
- Example: To raise 20 gallons to 0.1 mg/L phosphate, use 0.8 × 20 × 0.1 = 1.6 mL.
Suitable For
Freshwater planted aquariums, including aquariums containing shrimp and other invertebrates.
